1. An engine warming system for water cooled vehicles with coolant hoses and a radiator, comprising:
a first fluid exchange fitting having a first inlet port, a first outlet port, a second inlet port, and a second outlet port, with said first inlet port connected to a first vehicle coolant hose for inflow of vehicle coolant into said fitting, and said first outlet port connected to said first vehicle coolant hose for outflow of coolant into said coolant hose; said first fluid exchange fitting having a first position wherein a first passage is formed for the flow of a fluid between said first inlet port and said first outlet port; said first fluid exchange fitting having a second position wherein a second passage is formed between said first inlet port and said second outlet port and a third passage is formed between said second inlet port and said first outlet port; said first fluid exchange fitting selectively transitionable between said first position and said second position; a second fluid exchange fitting for in-line attachment to a hose in the cooling system of a second vehicle, said second fitting having a first inlet port, a first outlet port, a second inlet port, and a second outlet port, with said first inlet port connected to a second vehicle coolant hose for inflow of second vehicle coolant into said second fitting, and said first outlet port connected to said second vehicle coolant hose for outflow of coolant into said second vehicle coolant hose; said second fluid exchange fitting having a first position wherein a first passage is formed for the flow of a fluid between said first inlet port and said first outlet port of said second fitting; said second fluid exchange fitting having a second position wherein a second passage is formed between said first inlet port and said second outlet port and a third passage is formed between second inlet port and said first outlet port of said second fitting; said second fluid exchange fitting selectively transitionable between said first position and said second position; said first outlet port of said first fitting connectable by a first transfer hose to said second inlet port of said second fitting, and said second outlet port of said second fitting connectable to said second inlet port of said first fitting, so that when said first and second fluid exchange fittings are in said first position the cooling system of both vehicles function as originally designed, when said fittings are both in a second position, fluid from said first vehicle passes to said second vehicle, routes said coolant through the second vehicle cooling system filled with warm coolant, and returns said fluid to said first fitting second inlet port; wherein said first fluid exchange fitting further comprised of a first conduit, extending from said first inlet port to said to said first outlet port, said first conduit having a first valve capable of closing or opening said first conduit to flow of said fluid; said first fluid exchange fitting further comprised of a second conduit connected to said first conduit, with said second conduit having a second valve capable of closing or opening said second conduit for flow of said fluid from said first inlet port to said second outlet port; said first fluid exchange fitting further comprised of a third conduit connected to said first conduit, with said third conduit having a third valve capable of closing or opening said second conduit for flow of said fluid from said second inlet port to said first outlet port. |
